Woodmizer guide arm shield breaking
« on: December 07, 2017, 06:41:14 PM »
Anyone else experience this? This is the shield that is attached to both ends of the movable guide arm. It cups under to shield the blade on the idle side. The factory weld broke and has been welded back twice. I'm ready to cut the shield off.

Yep, been there.  You've got to make sure you get a good weld fillet on the back side of the bracket to keep it from vibrating.

My guy did that last time. But I could tell the shake was going to take it out again. Gonna cut that sucker off tommorow and not worry with it anymore. Just glad to know I wasnt the only one to see it.

Can't say I've seen it,, seen more than my share of vibration issues, but not that one.  My best guess is the material, higher carbon,  welded and then it cracks.  Lots of components for all kinds of machinery are made of recycled materials. If these are not QC'd, during the billeting  process, well, this is what you might get, high carbon steel has strength, but if not handled properly it can become very brittle. Just a guess, my suggestion would be to pull it off, heat it to a low cherry, then weld it back then, either pack it in sand or draw it back in the oven at 400°  might as well throw a tater in while your are working on it,  ;D
only have a few chain saws I'm not suppose to use, but will at times, one dog Dolly, pretty good dog, just not sure what for yet,  working on getting the gardening back in order, and kinda thinking on maybe a small bbq bizz,  thinking about it,

My mill had the blade guide shield "off"  (due to a mod) when I bought the mill, and I had it welded back on, no issues since!   ;)

Its history tommorrow morning. I grew up walking around a 0frick and miner edger without gaurds. Made it this long, I figure one less shield wont hurt. I still use that old miner.

You need a counter weight to take up the harmonics of the vibrations.

I would start with a strong magnet.
Just stick it on and watch your vibrations.
Move it around to find the magic spot.
I do this with my boring bar on my metal lathe to stop chatter.

I too am wondering why it is vibrating and where it is coming from?  Are you running Wood-Mizer B57 belts?

 Seems like most engines vibrate plenty at idle, not so bad when cutting.  Steve

 Have had to weld mine also a few times. Don't worry about it, keep sawing. If you're not sawing you sure aren't breakin' anything.  ;D ;D
